The British singer and songwriter, 23, granted a dying Dublin teen, Triona Priestley, her last wish only moments before she passed away.

Priestley, a huge fan of Sheeran as well as poetry, suffered from cystic fibrosis for years and, just last week, the end looked inevitable. Some of her friends quickly began a Twitter campaign, using the hashtag #songfortri.

Sheeran, known for his own songs such as "The A Team" (and for his famous friend Taylor Swift), ended up calling Priestley at her hospital just before lunch on Tuesday. He sang the 15-year-old her favorite song, his upbeat "Little Bird."
